Torque Converter Clutch And Drive Plate Inspection

Inspect the one-way clutch.

1. Set SST into the inner race of the one-way clutch.
   

   SST

   09350-32014(09351-32010)
   

2. Install SST so that it fits in the notch of the torque converter hub and the outer race of the one-way clutch.

3. Stand the torque converter up and turn SST.
   

   OK:

   The one-way clutch rotates freely when turned clockwise and locks when turned counterclockwise.
   

Inspect the torque converter assembly.
If any of the following problems is present, replace the torque converter assembly.

1. A metallic sound is emitted from the torque converter assembly during the stall test or when the shift lever is moved to N.
   
2. The one-way clutch turns freely or locks in both directions.
   
3. The amount of powder in the ATF is more than the sample shown in the illustration (refer to the sample).
   

   HINT:

   The sample shows approximately 0.025 liters (0.026 US qts, 0.022 Imp. qts) of ATF from a removed torque converter.

Replace the ATF in the torque converter.

HINT:

If the ATF is discolored or has a foul odor, stir the ATF in the torque converter before replacing it.

Clean and check the oil cooler and oil pipe line.

HINT:

1. If the torque converter is inspected or the ATF is replaced, it is necessary to clean the oil cooler and oil pipe line.
   
2. Blow compressed air (196 kPa (2 kgf/cm², 28 psi)) into the inlet hose.
   

1. If the ATF is cloudy, inspect the oil cooler (radiator).
   

Check the torque converter and oil pump gear for damage and deformation.
If there is any damage to the end of a bolt for the torque converter or to the bottom of a bolt hole, replace the bolt and torque converter.

NOTICE:

1. Make sure all of the bolts are the same length.
   
2. Bolts with washers must be used.
   

Set up a dial indicator and measure the runout at the 6 areas on the drive plate surface that contact the torque converter.

Maximum runout:

0.20 mm (0.0079 in.)
